JOSEPH A. MORIN, OF ST. HYAOINTHE, QUEBEC, CANADA MACHINERY FOR BEVELING WATCH-GEAR.

SPECIFICATION formingpart of Letters Patent No. 256,355, datedApril 11, 1882.

Application filed December 22, 1881. (No model.)

To all whom it may concern Be it known that I, JOSEPH ALFRED MORIN, of St. Hyacinthe, ofthe Province of Quebec, of the Dominion of Canada, haveinvented a new and useful Improvement in Machinery for Beveling Watch-Gears; and I do hereby de-' clare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a front elevation, and Fig. 2 a vertical and transverse section, of a machine embodying my invention. Fig. 3 is a rear view of its spindle-head and the mechanism for intermittently revolving it. Fig. 4 is a transin the claim hereinafter presented.

In the drawings, A denotes. the frame of the machine, it having within a horizontal bracket, B, extended from it, as shown, a rotary and vertically-movable spindle, O, pivoted at its foot upon a pedal or lever, D.

To the upper part of the spindle there is fixed a cylindrical head, E, in which is a circular recess, a, to receive a gear, F, to be beveled, the axis of the gear going between beveled studs b b, projecting up from the bottom of the recess. These studs prevent the gear from revolving within the recess.-

The gear is shown as having fivearins, there being to the head a like number of arms, 0, projectingfromits circumference and arranged at equal distances apart, as shown.

A flat ring, El, disposed above the bracket, and supported by standards d d erected there on, has projecting down from it an ear, 6, and a cam, f, arranged as represented, with a vertical and stationary angular cam, g, supported by the bracket.- On pressing the pedal downward, so asto force the spindle upward, one of the arms c of its head will be carried and moved against the cam f, and by it will be moved directly over the cam g, the head of the spindle being correspondingly turned. On allowing the spindle to drop downward-the arm will move down the inclined edge of the cam g, and by such the spindle-head will be further turned or revolved, it, while down on the bracket, being kept stationary thereon by the cam g, which then is between and-bearing against two of the arms 0. During each reciprocating movement of the pedal the spindlehead will be caused to make a partial revolution. The spindle-head, on being forced upward, abuts against and enters the ring H, an arm, 0, of such head entering into the notch or recess 73, between the ear e and the cam f. Such notch or recess serves to hold the head from turning while the gear may be in the process of being beveled.

Above the ring H are the beveling-cutters I or burrs I K, they being fixed'on two shafts, L M, arranged as represented. These shafts have beveled gears l, which engage withbevelgears Z 121, carried by two other shafts, N 0, arranged and connected by a universal joint, as represented. A driving-pulley, It, is fixed on the shaft N. On such pulley being revolved the cutters will simultaneously be put in'rapid revolution. The cutter I is for beveling the hub andvportiou's of two adjacent spokes of the gear, such cutter being conical and provided with teeth on its outer cutting-face to act against the edges of the spokes. This cutter also has a toothed concavity, 0, at its central part to receive and bevel the hub. Furthermore, the other cutter, K, is conical on its periphery and outer side,'it having teeth on each to enable it while being revolved to chamfer or bevel two of the spokes and theinner edge of that part of therim of the watch-gear that may be between them. On the spindle-head provided with a gear to be beveled being moved upward, the gear will be moved to the cutters, which, entering two spaces on opposite sides of the hub, will, while revolving simultaneously, be caused to bevel down the hub, the spokes, and the rim. Each time the spindle is dropped and again forced upward other portions of the gear may be beveled in like manner until all its spokes, hub, and rim may have been beveled t0 the necessary extent.

Iclaim as my invention in the described machine- The combination of the revoluble and recessed vertically-moiproeating carrying-head E, having the series of arms 0, as set forth, with the stationary ring H, and cams e,f, and

g,an 1 with the 'cutters I and K, provided with I0 mechanism for revolving them, all being substantially and to operate and for the purpose as specified.

JOSEPH ALFRED MORIN.
